# Cobalt Grid
> Electric cobalt italic serifs on a graph-paper canvas, anchored by stair-stepped pixel-glitch decorations and slim hairline rules.
A single self-contained HTML deck — typography, palette, decorative system, and slide vocabulary are all tuned together. Mixing layouts across templates breaks the system; stay inside this one.
## At a glance
- **Scheme:** light - **Formality:** high - **Density:** medium - **Slides in demo:** 8
## Best for
Anything that should feel like a quietly serious design / research bulletin, art publication, or curated trend report. Strong for studio annuals, agency capabilities decks, design-research publications, architecture / art / academic decks, and any deck wanting one strict accent colour and a printed-ledger calmness rather than corporate polish.
## Avoid for
Decks that need warmth, multi-colour energy, or a casual / playful voice — the strict cobalt + cream + grid palette is intentionally austere.
## Workflow
1. **Clone `example.html`** into the user's workspace as the working file. 2. **Replace placeholder content** with the user's real headlines, body copy, numbers, names, dates, and section labels. Match existing dimensions when swapping image placeholders. 3. **Preserve the design system.** Never substitute fonts, recolor the palette, restructure the layout grid, or strip decorative elements (corner brackets, paper grain, geometric shapes, illustrated SVGs). They are part of the identity. 4. **Adjust deck length by duplicating layouts.** If the user has more content than the demo holds, duplicate an existing slide of the most appropriate layout. If less, drop slides from the bottom. Update page-number labels. 5. **Designing missing layouts:** if a slide needs a layout the template doesn't have, design it from scratch using the same fonts, palette, decorative vocabulary, spacing rhythm, and component grammar — never bail to a different template. 6. **Keep the navigation runtime as shipped.** If the deck ships an `assets/deck-stage.js` or inline keyboard handler, leave it intact.

# Cobalt Grid
> Electric cobalt italic serifs on a graph-paper canvas, anchored by stair-stepped pixel-glitch decorations and slim hairline rules.
A single self-contained HTML deck — typography, palette, decorative system, and slide vocabulary are all tuned together. Mixing layouts across templates breaks the system; stay inside this one.
## At a glance
- **Scheme:** light - **Formality:** high - **Density:** medium - **Slides in demo:** 8
## Best for
Anything that should feel like a quietly serious design / research bulletin, art publication, or curated trend report. Strong for studio annuals, agency capabilities decks, design-research publications, architecture / art / academic decks, and any deck wanting one strict accent colour and a printed-ledger calmness rather than corporate polish.
## Avoid for
Decks that need warmth, multi-colour energy, or a casual / playful voice — the strict cobalt + cream + grid palette is intentionally austere.
## Workflow
1. **Clone `example.html`** into the user's workspace as the working file. 2. **Replace placeholder content** with the user's real headlines, body copy, numbers, names, dates, and section labels. Match existing dimensions when swapping image placeholders. 3. **Preserve the design system.** Never substitute fonts, recolor the palette, restructure the layout grid, or strip decorative elements (corner brackets, paper grain, geometric shapes, illustrated SVGs). They are part of the identity. 4. **Adjust deck length by duplicating layouts.** If the user has more content than the demo holds, duplicate an existing slide of the most appropriate layout. If less, drop slides from the bottom. Update page-number labels. 5. **Designing missing layouts:** if a slide needs a layout the template doesn't have, design it from scratch using the same fonts, palette, decorative vocabulary, spacing rhythm, and component grammar — never bail to a different template. 6. **Keep the navigation runtime as shipped.** If the deck ships an `assets/deck-stage.js` or inline keyboard handler, leave it intact.

Decks that need warmth, multi-colour energy, or a casual / playful voice — the strict cobalt + cream + grid palette is intentionally austere.
## Workflow
1. **Clone `example.html`** into the user's workspace as the working file. 2. **Replace placeholder content** with the user's real headlines, body copy, numbers, names, dates, and section labels. Match existing dimensions when swapping image placeholders. 3. **Preserve the design system.** Never substitute fonts, recolor the palette, restructure the layout grid, or strip decorative elements (corner brackets, paper grain, geometric shapes, illustrated SVGs). They are part of the identity. 4. **Adjust deck length by duplicating layouts.** If the user has more content than the demo holds, duplicate an existing slide of the most appropriate layout. If less, drop slides from the bottom. Update page-number labels. 5. **Designing missing layouts:** if a slide needs a layout the template doesn't have, design it from scratch using the same fonts, palette, decorative vocabulary, spacing rhythm, and component grammar — never bail to a different template. 6. **Keep the navigation runtime as shipped.** If the deck ships an `assets/deck-stage.js` or inline keyboard handler, leave it intact.
